Evaluation of Lung Deposition of Aerosol Via HFNC in Healthy Adults

Not Applicable

• Conditions: Healthy

• Registration Number: NCT02519465
• Lead Sponsor: Universidade Federal de Pernambuco

Brief Summary

The aerosol associated with noninvasive ventilation (NIV) and high flow therapy with nasal interface have been employed in an attempt to relieve respiratory distress and optimize the deposition of drugs by inhalation.

Some studies report the effects of NIV association with fogging in healthy subjects, asthmatics and COPD 7.8, but studies evaluating the association between high flow nasal mist interface and therapy are scarce and most are found in vitro and animal models. The objective of this study is to evaluate the deposition of the aerosol scintigraphy using the high flow nasal interface system with vibrating mesh nebulizers using in healthy adults.
